Started up 2015 Roadmaster yesterday and as I started to roll off the horn honked once. Went about 50 feet and it honked again, another 50 ft another honk. Stopped the bike after the fourth honk and turned it off. Started it back up and no more honks. Is there something that I am doing wrong on startup to cause this to happen? This happened twice before the 500 mile service was done. I had the FAB battery replaced about a month ago when I had the 500 mile break-in service performed. Technician said the readout showed the FAB battery was low and told me that that could caused the horn to go off and a red shield to display on the dash which is what happened on the two occasions before the 500 mile service. I have not had that happen again since the FAB battery was replaced until yesterday. I didn't notice whether the red shield on the dash lit up, I just turned off the bike and restarted it and no more horn going off???? What the heck?
